Abstract: A wheel hub rotary joint assembly includes a wheel hub with a wheel flange and a sleeve section for receiving a wheel bearing; and a constant-velocity rotary joint with an outer joint part having a first spur gearing section with first teeth at its end facing the wheel hub. The sleeve section has a second spur gearing section with second teeth at its end facing the rotary joint. The two spur gearing sections engage one another for torque transmission. At least one of the two spur gearing sections is designed such that, viewed in the radial direction, the first and second teeth initially only come into contact with one another on a small subsurface of the tooth surfaces facing one another during axial tensioning.

Abstract: A wheel hub rotary joint assembly with an axis of rotation includes a wheel hub with a wheel flange for connecting a wheel and a sleeve section for receiving a wheel bearing; a constant-velocity rotary joint with an outer joint part, an inner joint part and torque-transmitting elements. The outer joint part has a first spur gearing section with first teeth at its end facing the wheel hub. The sleeve section has a second spur gearing section with second teeth at its end facing the constant-velocity rotary joint. The two spur gearing sections engage with one another for torque transmission. A tensioner for axially tensioning the wheel hub against the outer joint part is axially supported on one side on the wheel hub and on the other side on the outer joint part.

Abstract: A continuously variable friction roll toroidal drive includes two variator disks which are rotatable about a common roll axis and which have tracks which are part of the circumferential surface of a torus concentric with the variator roll axis, and a plurality of rollers in contact with the tracks, each being mounted for rotation in a housing with which a support is associated. The axis of rotation of each roller being able to turn about an axis which is inclined at a certain angle to the center plane of the torus. The direction of the action of the support of each roller lies in the center plane of the torus. Each roller is mounted for rotation on a turning body. The turning body is mounted for turning in the housing, the axis of rotation of the turning body being inclined at a certain angle to the center plane of the torus.
